Procedure

To a stirred solution of 6-bromo-1-isopropyl-N-((4-(methoxymethyl)-6-methyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-1H-pyrazolo[3,4-b]pyridine-4-carboxamide (0.06 g, 0.133 mmol) and (2,2,6,6-tetramethyl-1,2,3,6-tetrahydropyridin-4-yl)boronic acid (0.043 g, 0.160 mmol) in dioxane/water mixture (1.5 mL+0.5 mL), Na2CO3 (0.5 g, 0.5 mmol) was added and solution purged with argon for 15 min. Then Pd(PPh3)4 (0.008 g, 0.007 mmol) was added and argon was purged again for 10 min. Reaction mass was heated at 100° C. for 2 h. On completion, reaction mixture was diluted with water and extracted with 10% MeOH/DCM. Combined organic layers were dried over Na2SO4 and solvent removed under reduced pressure to obtain crude material which was purified by column chromatography over silica gel to afford the desired product (44% yield). LCMS: 507.25 (M+1)+; HPLC: 99.64% (@ 254 nm) (Rt; 5.159); 1H NMR (DMSO-d6, 400 MHz) δ 11.68 (bs, 1H), 8.91 (t, 1H), 8.26 (s, 1H), 7.77 (s, 1H), 6.80 (s, 1H), 6.09 (s, 1H), 5.24-5.18 (m, 1H), 4.51 (s, 2H), 4.35 (d, 2H, J=4.4 Hz), 3.32 (3H merged in DMSO peak), 2.43 (s, 2H), 2.17 (s, 3H), 1.49 (d, 6H, J=6 Hz), 1.24 (s, 6H), 1.14 (s, 6H).
